Which of the following are appropriate techniques to achieve the expected output in the Function...

The correct techniques are Random function identification and FAST diagramming . In the Function Analysis Phase, the team must shift away from describing components, designs, or solutions and instead define what the project, product, or process must do . SAVE’s Value Methodology Standard states that this phase defines project functions using a two-word active verb / measurable noun format and analyzes those functions to determine which require improvement, elimination, or creation. This directly supports random function identification, commonly aligned with Random Function Definition, where the team identifies functions in verb-noun form before classifying and organizing them.

FAST diagramming is also a core Function Analysis technique. The standard function-analysis sequence includes building a function model as a Function Analysis System Technique (FAST) diagram , and the SAVE glossary defines a FAST diagram as a graphical representation of dependent function relationships using How/Why logic. Detailed cost analysis is not the primary technique here; cost is allocated to functions after functions are defined. A paired comparison matrix is more typical of evaluation/prioritization, and a process flowchart belongs more naturally in information/process understanding rather than function modeling.
